Overview
Water Cycle and the Circular Economy
4
“A circular economy is an industrial system that is
restorative or regenerative by intention and design. It
replaces the end-of-life concept with restoration, shifts
towards the use of renewable energy, eliminates the use
of toxic chemicals, which impair reuse and return to the
biosphere, and aims for the elimination of waste through
the superior design of materials, products, systems and
business models.”World Economic Forum
What is the Circular Economy?
5
The circular economy is built around three key
principles:
Preserving and enhancing natural
capital by controlling finite stocks and
balancing renewable resource flows
The Circular Economy Butterfly Diagram
A Circular Economy characterisation (source Ellen MacArthur Foundation 2016)
Optimising resource yields by
circulating products (use of
renewables, recycling, re-use, better
maintenance of products, sharing
products)
Fostering system effectiveness by
designing out negative externalities
(waste which cannot be used).

• The Water Cycle is a system ripe for Circular Economy thinking
• Focusing on the Water Cycle (Urban and Catchment) can enable and enhance discussions around Circular Economy at local, cityand regional scales.
• Understanding the governance across the Water Cycle is important if we are going to maximise the value of Circular Economy thinking.
• How do we bring together the thinking on Water Cycleand Circular Economy concepts and frameworks?

• Share assets (e.g. cars, rooms, appliances)
• Reuse/secondhand
• Prolong life through maintenance, design for durability, upgradability, etc.
• Increase performance/efficiency of product
• Remove waste in production and supply chain
• Leverage big data, automation, remote sens- ing and steering
• Shift to renewable energy and materials
• Reclaim, retain, and restore health of ecosys- tems
• Return recovered biological resources to the biosphere
SHARE
OPTIMISE
ReGENERATE
• Dematerialise directly (e.g. books, CDs, DVDs, travel)
• Dematerialise indirectly (e.g. online shop- ping)
• Replace old with advanced non-renewable materials
• Apply new technologies (e.g. 3D printing)
• Choose new product/service (e.g. multimodal transport)
• Remanufacture products or components
• Recycle materials
• Digest anaerobically
• Extract biochemicals from organic waste

understand it better to make the most of Circular Economy
thinking eg Yorkshire
Yorkshire Water• Key assets types include: water and wastewater Treatment works,
water distribution networks, sewerage, abstractions, pumping stations, outfalls and reservoirs.
• Geographical distribution of assets is fairly even across Yorkshire although there is a cluster in the Leeds-Bradford and Sheffield urban areas.
Environment Agency• Involved in the natural components of the water cycle.
• Key assets include: flood defences, weirs, abstractions, pumping stations and reservoirs.
• Fairly even spread across Yorkshire with clusters of assets around areas liable to flood, e.g. lower Aire Valley and River Hull.
Canal & River Trust• Key assets include: canals, locks, reservoirs and fish passes.
• Majority of the CRT assets are in the South of the county in fairly discrete corridors
• Historically distributed between trading towns in South & West Yorkshire and Lancashire.
Internal Drainage Boards• Key assets include: pumping stations (owned and/or operated).
• Map shows the area of responsibility of the Internal Drainage Boards.
• There are 42 IDBs within the Yorkshire Water area. Typically distributed through low lying areas, e.g. Vales of Mowbray, York, Pickering, and along River Hull
Local Authorities• Key assets types include: highways drainage, pumping stations,
outfalls and reservoirs.
• Majority of the assets are situated in the West and South of the Yorkshire region and in particular around the urban centres of Leeds, Bradford and Sheffield.
Network Rail• Key assets include: railway drainage infrastructure.
• The assets are located along 1,387 km of railway lines, mainly in the West and South of the county in fairly discrete corridors.
• Network Rail (NR) core function is the management and maintenance of railways. Their influence on the water cycle is limited.
Highways Agency• Key assets include: motorways and major trunk roads drainage
infrastructure.
• The assets are located along 654 km of roads, mainly in the West and South Yorkshire in fairly discrete corridors.
• HA core function is the management and maintenance of roads. Their influence on the water cycle is limited.
Private Owners• In addition there are a series of private owners of assets that
may be of strategic interest.

CELSIUS CITY
The Celsius City project - aimed at
harvesting energy
Funded with £20 million from the EU
Will build heat exchangers to extract heat
from water flushed down the drain.
Demonstrating the technology using a
series of heat exchangers in the sewer
system in Cologne, Germany
Harvest the heat for use in schools and
gyms.
The first plant - 1.2 million kilowatt
hours in a year – enough to heat 70
family homes.

Veolia: A new way to make plastics
Bio-refining : Using wastewater as a feed stock to make plastics
25
In wastewater treatment plants in
Belgium, the Netherlands, and
Denmark, Anoxkaldnes, a subsidiary of
Veolia, is running pilot prototyping for
the production and recovery of
Polyhydroxyalkanoates (PHA) – an
intermediate material used to produce
bioplastics.

Conclusions
12
A. Think about applying circular economy thinking across the whole water
cycle
B. Start using consistent language: Reduce, Reuse, Recycle, Share, Regenerate,
Refurbish and Resource
C. Share more examples of what has worked – and what hasn’t
D. Look across other applications of circular economy thinking in other sectors
for insight and learning
E. Bring all the players across the water cycle on-board with the thinking and
stimulate innovation through pilot/trial initiatives
F. Show the relevance of circular economy thinking to other emerging
concepts eg Water-Wise Cities (IWA)
